### hasFlags
|
|
|
|
Check if the current process's arguments contain the specified flags.
|
|
|
|
Use `Array.every()` and `Array.includes()` to check if `process.argv` contains all the specified flags.
|
|
Use a regular expression to test if the specified flags are prefixed with `-` or `--` and prefix them accordingly.
|
|
|
|
```js
|
|
const hasFlags = (...flags) =>
|
|
flags.every(flag => process.argv.includes(/^-{1,2}/.test(flag) ? flag : '--' + flag));
|
|
```
|
|
|
|
```js
|
|
// node myScript.js -s --test --cool=true
|
|
hasFlags('-s'); // true
|
|
hasFlags('--test', 'cool=true', '-s'); // true
|
|
hasFlags('special'); // false
|
|
```
